Quoted from Lhyrgoif:Never had the need to buy a separate DMD display but realized a standard DMD is about 300$, for 100$ more I can get a ColorDMD so if I do the replacement path it will probably be in color.
You can likely also find a new or used monocolor LCD/LED display for $100-$150 which will be completely silent in operation. Since this is a low voltage display, it will not use any of the HV components on the driver board; you can and should remove both fuses from the board at this point.
